Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly technology, and in particular to a securely mounted vehicle handle and a vehicle including the handle. Background Technology

[0002] Currently, for motorcycles, electric bicycles, or other vehicles that use handlebars to control direction, the handlebars are generally fixed to the front of the vehicle using a clamping method. Specifically, the cylindrical handlebar is inserted into the front of the vehicle, and then clamped by two parts that fit together vertically or horizontally, and tightened with bolts to secure the handlebar to the front of the vehicle. The tightness of the handlebar installation can be adjusted by adjusting the tightening force of the bolts.

[0003] However, in actual use, due to vibrations caused by vehicle movement, the bolts used to clamp the handlebars may loosen, resulting in an unstable handlebar installation and even a risk of it falling off. Therefore, users often need to check the bolt tightness and tighten them, leading to a less than ideal driving experience. Furthermore, because bicycle handlebars require a certain structural strength, they are typically made of smooth steel tubing. Simple clamping methods often fail to hold the handlebars securely, causing them to rotate easily under circumferential forces and detach from the clamping mechanism under tension, resulting in insufficient installation stability.

[0026] Currently, for motorcycles, electric bicycles, or other vehicles that use handlebars to control direction, the handlebars are generally fixed to the front of the vehicle using a clamping method. Specifically, the cylindrical handlebar is inserted into the front of the vehicle, and then clamped by two parts that fit together vertically or horizontally, and tightened with bolts to secure the handlebar to the front of the vehicle. The tightness of the handlebar installation can be adjusted by adjusting the tightening force of the bolts.

[0027] However, in actual use, due to vibrations caused by vehicle movement, the bolts used to clamp the handlebars may loosen, resulting in an unstable handlebar installation and even a risk of it falling off. Therefore, users often need to check the bolt tightness and tighten them, leading to a less than ideal driving experience. Furthermore, because bicycle handlebars require a certain structural strength, they are typically made of smooth steel tubing. Simple clamping methods often fail to hold the handlebars securely, causing them to rotate easily under circumferential forces and detach from the clamping mechanism under tension, resulting in insufficient installation stability.

[0028] In response, this application proposes a securely mounted bicycle handlebar. The upper and lower shells are locked together at only one end using a locking bolt, while the other ends are joined together as a fulcrum. Based on the lever principle, tightening the locking bolt at one end clamps and secures the handlebar located in the middle, making this fixing method more stable and reliable. Furthermore, a limit pin is provided in the second clamping part to restrict the handlebar's circumferential rotation and axial movement. The interference fit between the limit pin and the upper limit hole on the handlebar further restricts the handlebar's free movement.

[0029] In addition, this application also proposes a vehicle that includes the aforementioned securely mounted handlebars.

[0030] Reference Figure 1 and Figure 2 The securely mounted bicycle handlebar in the first embodiment of this application includes an upper shell 100, a lower shell 200, a handlebar 400, and a locking bolt 500. The upper shell 100 and lower shell 200 together constitute the main structure of the securely mounted bicycle handlebar. They are joined together to form a housing, which can house the electronic equipment in the handlebar and also serves to clamp and secure the handlebar 400. The handlebar 400 is inserted into the housing formed by the upper shell 100 and lower shell 200, with a portion extending out of the housing for the user to grip. The locking bolt 500 passes through the upper shell 100 and lower shell 200, locking them together and acting as a fastener.

[0031] Specifically, refer to Figure 3 The upper shell 100 extends from a first end along the x-direction to a second end. A first mounting hole 110 is provided at the first end of the upper shell 100, and a first clamping portion 120 is provided in the middle of the upper shell 100. The lower shell 200 extends from a first end along the x-direction to a second end. A second mounting hole 210 is provided at the first end of the lower shell, and a second clamping portion 220 is provided in the middle of the lower shell 200. Notably, the second clamping portion 220 is provided with a limiting pin 221 extending along the z-direction, and a clearance groove 222 is provided at the root of the limiting pin 221.

[0032] Furthermore, referring to Figure 4 A gap 300 is left between the first end of the upper shell 100 and the first end of the lower shell 200, and the second end of the upper shell 100 is attached to the second end of the lower shell 200.

[0033] The handle 400 is inserted into the space between the first clamping part 120 and the second clamping part 220, as shown in the reference. Figure 5 The handle 400 has a limit hole 410 on its side, and the limit pin 221 is interference-fitted with the limit hole 410.

[0034] The locking bolt 500 passes through the first mounting hole 110 and the second mounting hole 210. By tightening the locking bolt 500, the first clamping part 120 and the second clamping part 220 clamp the handle 400.

[0035] The working principle of this securely installed bicycle handlebar is as follows: After the handlebar 400 is inserted into the space between the first clamping part 120 and the second clamping part 220, tightening the locking bolt 500 reduces the gap 300 between the upper shell 100 and the lower shell 200. The first clamping part 120 and the second clamping part 220 apply force to the side of the handlebar 400, thus clamping and fixing the handlebar 400. Furthermore, the second ends of the upper shell 100 and the lower shell 200 fit together, forming a fulcrum in the lever structure. Based on the lever principle, the handlebar 400 can be clamped more tightly by the first clamping part 120 and the second clamping part 220, thereby reducing the risk of the handlebar 400 loosening. A limiting hole 410 is provided on the side of the handlebar 400, and the limiting pin 221 in the second clamping part 220 can be inserted into the limiting hole 410 to limit the axial displacement of the handlebar 400 (in this application, the axial direction of the handlebar 400 is the length direction of the handlebar 400). Moreover, the limiting pin 221 and the limiting hole 410 are interference fit, so the limiting pin 221 is not easy to loosen after being inserted into the limiting hole 410, and has a more stable fixing effect.

[0036] In this application, since the limiting pin 221 and the limiting hole 410 adopt an interference fit, the limiting pin 221 will inevitably deform. This deformed portion will accumulate at the root of the limiting pin 221 during insertion. If a corresponding groove is not provided, this portion will abut against the end face of the limiting hole 410, thus preventing the limiting pin 221 from being inserted into place and hindering assembly. Therefore, this application provides a clearance groove 222 at the root of the limiting pin 221 to accommodate the deformed portion of the limiting pin 221.

[0037] Specifically, the outer diameter of the 400 handle is Φ mm, the inner diameter of the contour enclosed by the first clamping part 120 and the second clamping part 220 is Φ mm, the width of the gap 300 left between the first end of the upper shell 100 and the first end of the lower shell 200 mm. Furthermore, B≥0.1mm, to avoid the gap 300 being too small so that when the locking bolt 500 is tightened, the gap 300 decreases to zero, but the first clamping part 120 and the second clamping part 220 still fail to clamp the handle 400 in place.

[0038] Specifically, in some embodiments, the second end of the upper shell 100 is connected to the second end of the lower shell 200, so that the upper shell 100 and the lower shell 200 together form an integral structure. In other embodiments, the second end of the upper shell 100 and the second end of the lower shell 200 can be connected by bolts, snap-fit ​​connections, pin connections, etc. It is worth noting that the second end of the upper shell 100 and the second end of the lower shell 200 are kept in a fitted state. In this embodiment, the second end of the upper shell 100 and the second end of the lower shell 200 are fastened together by bolts.

[0039] Furthermore, the side of the limiting pin 221 is provided with multiple reinforcing ribs, which contact the inner wall of the limiting hole 410. Thus, when the limiting pin 221 is inserted into the limiting hole 410, the reinforcing ribs replace the surface of the limiting pin 221 to fit against the inner wall of the limiting hole 410. Compared to surface-to-surface contact, line-to-surface contact is more conducive to interference fit assembly and reduces assembly difficulty. Simultaneously, the portion of the reinforcing rib deformed by compression can be deposited into the relief groove 222 at the root of the limiting pin 221, ensuring that the limiting pin 221 can be inserted into the correct position.

[0040] The specific number of reinforcing ribs can be two, three or more. It is worth noting that each reinforcing rib extends along the z-direction and is set on the surface of the limiting pin 221. Each reinforcing rib is arranged in a circular array around the central axis of the limiting pin 221. Thus, when the limiting pin 221 is inserted into the limiting hole 410, the resultant force on all the limiting pins 221 is zero, ensuring that the limiting pin 221 is uniformly stressed and fixed in the center of the limiting hole 410.

[0041] Furthermore, the end of the limiting pin 221 is chamfered to facilitate its entry into the limiting hole 410 during assembly. The chamfer can be a beveled chamfer or a rounded chamfer; the specific structure will not be described in detail here.

[0042] Specifically, the diameter of the limiting hole 410 is Φ mm, the diameter of the limiting pin 221 is Φ mm, ensuring that the diameter of the limiting pin 221 is larger than the diameter of the limiting hole 410. Wherein, ES≤0.2mm.

[0043] Furthermore, the relief groove 222 is annular, the inner wall of the relief groove 222 is connected to the root of the limiting pin 221, and the diameter of the outer wall contour of the relief groove 222 is Φ(E+3)mm.

[0044] A vehicle according to a second aspect of this application includes a vehicle body and the aforementioned securely mounted handlebars, the securely mounted handlebars being mounted into the vehicle body.

[0045] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
